Great suggestion, very cool site! Someone should submit this as a HN link. Pretty useful resource for hackers I think. I have like 70 domains that are just sitting around with lame Godaddy parking pages (with godaddy adwords). I'll probably spend some time tomorrow and just convert them all to LaunchSplash parking pages.

launchsplash looks cool.

And once you've collected the names, you could use something like http://campaignmonitor.com/ to send email blasts.
